In today's hydraulic and lube systems, technology is changing more and more to be compact, with
higher efficiency, and lighter weight.
Where this can serve to help organizations carry more machines in their fleet, and ultimately
save space, there are some down falls that come with the good.
Some of the issues that arise with reducing size, raising efficiency, and decreasing weight
include:
Tighter tolerance hydraulic components that are more sensitive to contamination
Less-than ideal reservoir size and shape for fluid life and preservation
Hotter oil temperatures and higher running oil pressures within the system
These conditions can evolve into more unforgiving consequences such as:
Premature component failure Poor and irregular hydraulic system response
Foaming of the oil and pump cavitation Insufficient resonance time in the reservoir
for the air to release and foam to collapse Shortened fluid lifespan due to increased
oxidation
Given the issues that Modern hydraulic systems have to contest with, let's not add problems
caused by unnecessary contamination to the list of problems as well!
During today's video, we will be going over the importance of properly sizing a filtration
solution to your machine's exact requirements.
A proper solution will correspondingly help fix some of those negative situations we mentioned
before.
As we go through our comprehensive "7 Steps to Choosing the Correct Filtration Solution",
keep in mind all of the negative situations we mentioned before, and how they are addressed
with a simple, yet highly-efficient filtration solution from Schroeder Industries.
Step 1 is to determine the operating pressures of the system you are applying the filtration
solution to.
While determining the system's pressure, you must keep in mind these three factors:
The environment the system is going to be operating in (dirty, clean, outside, inside,
and mobile) Where the filtration solution will be installed
The duty cycles the filtration will see.
These are all important to note when finally picking a solution.
Step 2 is to determine the flow rates within the system needing filtration.
Questions you need to ask yourself are:
What are the max and nominal flow rates that the system sees?
Is there any type of surge or back flow present in my system?
These questions will lead you to finding the correct element sizing and material needs.
Step 3 is to figure out what your most valuable component is.
What we mean by that is, what component in your system requires the lowest (or cleanest)
ISO code reading?
It never hurts to pick an ISO code that is lower than the smallest ISO code you need.
If you are unsure of what ISO code you need, think of components that are breaking down/wearing
out the fastest.
As a note, we have charts available for general component ISO code levels for just about any
part you are looking for.
The component OEM's will also list ISO Code cleanliness recommendations
in their own product catalogs if you are looking for a more precise code for your system.
Step 4 is to use the ISO code you found in Step 3, and match it to a micron rating.
Each ISO code has a specific micron rated filter element you should use to best capture
and retain the size of contamination most prevalent in your system.
Using this chart will guide you to choose the correct micron rating.
If you are between ratings, remember you can go to the lower ISO code.
Step 5 is to recognize the fluid you are using.
The type and viscosity of fluid that runs in your system will help you determine the
seal type, media type, and contamination type you are experiencing the most problems with.
At Schroeder, we offer media solutions for mineral-based oils and fuel that remove solid
contamination, water, and even electrostatic discharge!
There is a filter for all!
Step 6 is to determine your maximum operating temperature.
Temperature will help verify the use of the proper housing size and, more importantly, viscosity
Viscosity will affect the differential pressure, and will need close attention.
Knowing your working and "cold-start" temperature is very important.
Step 7 is to piece it all together.
With all the information gathered from Steps 1-6, you can calculate the overall system
differential pressure.
If all pieced together correctly, your solution should result in your clean element pressure
drop being less than half of the overall bypass cracking pressure at normal operating temperature
and flow.
Remember to note the porting options you need for your specific system, and if you would
like any contamination indicator options too.
Today's compact and light weight hydraulic systems sure do have a lot to worry about.
It's best that operators and fleet owners do not let contamination be a problem.
After following and implementing Schroeder's "7 Steps to Choosing the Correct Filtration
Solution", you will begin to see the results fairly quickly.
Results such as:
Seeing cleaner fluid System components lasting longer
Oil life extension Reduction in maintenance intervals
These all should be positive effects of your new Filtration Solution.
